Special Issue Information
Dear Colleagues,
The plant kingdom is the main source of chemical diversity from which hundreds of organic molecular frameworks are produced, which means several thousands of compounds and hundreds of new molecules are discovered every day in industrial and academic laboratories around the world.
Nature still remains the most efficient and imaginative “synthetic chemist”, and this impressive mass of chemical knowledge is the grounds for the development of a potentially infinite number of new applications in the contexts of agriculture, food science, and pharmacology, without neglecting the very interesting new applications of plant products in the preservation of cultural heritage artefacts.
The isolation and chemical characterization of new complex structures remain fascinating challenges for natural product researchers.
The present Special Issue will be addressed mainly, but not exclusively, to presenting the most recent results concerning new applications (nutraceutical, biological, pharmacological, etc.) of plant extracts, essential oils, and pure compounds isolated from plants; the description of previously unknown phytochemical profiles of plant species; and the structural elucidation of non-banal new molecules from plant extracts.

Abstract: Annatto, obtained from the seeds of achiote (Bixa orellana L.), is a widely used orange pigment rich in bixin and other apocarotenoids. This work introduces the optimisation of a green extraction method of pigments and antioxidant compounds from achiote as well as its integration in a one-step green extraction-cosmetic formulation process. A biphasic solvent system of oil and water was used to recover simultaneously polar polyphenols, and less polar compounds, such as δ-tocotrienol and bixin. The optimisation of the ultrasound assisted extraction is presented, as well as a comparison of different vegetable oils used as solvents of extraction. The composition, physico-chemical properties and antioxidant activity of the oils were studied and their extraction performance was compared. Refined sunflower oil prove to be a better solvent than virgin olive, jojoba, coconut and grapeseed oils. Both aqueous and oil phases displayed an interesting antioxidant capacity. The oil phase contained 0.9% of bixin, as well as minor apocarotenoids and δ-tocotrienol. Twelve compounds, mainly phenolics, were identified by UHPLC-DAD-HRMS/MS in the aqueous phase. Twenty-one volatile compounds were identified in the volatile fraction by SPME-GC-MS. Lastly, a one-step green process is proposed to combine the extraction and the cosmetic formulation of the bioactive compounds.
